GIMP dialog boxes take forever to load!

Hello, I've been using GIMP for years and have never had this issue. Recently, with no change to system, every time I use anything that requires a dialog box to open (file>open, edit>preference, etc). It literally takes about a minute to load the actual dialog box. I tried upgrading to 2.10, when that didn't work, I went back to 2.8. I also tried a different folder to open within (one with few files), disconnected some external drives, etc. I'll post a photo of my system. any help would be appreciated!
